摘要
对微机通信中有关文件传输中的常用协议 ,即Xmodem协议、Ymodem协议、Zmodem协议和KER MIT协议等进行了较详细的分析和比较 ,并对通用性好、性能较优越的日趋国际标准的KERMIT协议 ,提出了一种改进方案 ,使其在文件传输中断时从中断点处开始恢复传输 ,保证无差错无重复地进行通讯 ,并且在 2台直接相连的 5
In this paper several file transfer protocol, Xmodem, Ymodem, Zmodem, and Kermit were analyzed and compared in detail. An enhanced proposal was put forward for Kermit, which has better compatibility and performance and spreads nearly worldwide. It assures repeated communication without fault when file transfer recovers from break point. An experiment program was carried out between two 586 PCs in C language and it proved true. In the program, it is to control serial port communcation directly. .
